Mission-Critical 4-Socket Server

The Dell PowerEdge R940 is a 3U rack server built for heavy database and virtualization workloads. It ships with four Intel Xeon Gold 5120 processors running at 2.2 GHz with 14 cores each and 768 GB of DDR4 registered ECC memory across 24 modules. Dual 400 GB SATA SSDs sit behind a PERC H730P controller with battery-backed cache supporting RAID 0, 1, 5, 6, 10, 50 and 60.

Scale-Up Buyers vs Scale-Out Needs

This system suits teams that need maximum cores and memory in a single 3U chassis with redundant 1600 W power supplies and iDRAC9 Enterprise management. Buyers who want more storage bays than the eight 2.5-inch slots provided or who prefer a scale-out cluster of smaller nodes should look at a different platform.

Four-Socket Ceiling Decides Fit

The R940 supports a maximum of four processors, and this unit already populates every LGA 3647 socket. If your workload demands room to add CPUs later, this configuration cannot grow further.

Questions about this item

How do I install the 24 DDR4 memory modules into the 48 slots, and which population rule do builders often miss?

Fill all 24 modules across the 48 slots following the per-processor channel sequence shown in the system service manual; the common error is leaving a channel unbalanced within a single CPU.

Which components will need replacement first during the server's service life?

The two 400 GB SATA SSDs and the PERC H730P controller battery are the primary field-replaceable items with defined wear-out cycles.

What thermal limit appears first when all four Xeon Gold 5120 processors run at 3.2 GHz turbo continuously?

The 1600 W redundant power supplies reach their sustained output ceiling before the chassis cooling hits its maximum capacity.
